Abstract (en)
[origin: WO2014000818A1] The invention relates to the Authorized Shared Access (ASA) concept in which a source node temporarily uses ASA spectrum as secondary user and on request of an ASA controller said ASA spectrum needs to be cleared (evacuated) and made available to a primary spectrum user and thus target nodes have to be selected by the source node to take over traffic from the source node; the source node thus obtains resource information of at least one target node for the spectrum clearance, choose at least one target node for clearance traffic transfers based on the resource information of the at least one target node, inform the chosen at least one target node about the coming traffic transfers, and transfer traffic by using a handover procedure; the target node reserves resources after receiving the information about the coming traffic transfers.
